Rating list and tables. (In the rating list you will see rating changes since the previous report).

(This is my personal selection, where I include only well-tested free single-CPU engines. If you like, you can alter this selection, or even make completely different one using our web-site.)

Changes since the last report:

1. Hamsters 0.5 was added, ranked #38 currently! (among free single-CPU engines).

2. Abrok 5.0 was added, rating of 2561 and ranked #42.

3. Movei 0.08.438(10 10 10) was tested - 10 10 10 is an improved personality suggested by Uri. This new version is right now 101 points higher than Movei 0.08.403! As a result Movei is currently #7 Free Single-CPU engine!

4. Lot of gap-filling to extend the tested area to 16 cells up and down from diagonal.

Engines to be tested and added in future:

• Sjeng 12.13
• BugChess2 (suggested by author)
• Twisted Logic 20070915 (suggested by author)
• Spiderchess
• Arasan 64-bit
• Comet
• Pepito
• Nejmet
• King of Kings
• Dragon
• Patzer
• Petir 4.999999
• Colossus 2007d
• Fruit 2.3.3
• Toga (Don't know yet which version to test, probably 1.3.1 default)
• Delfi 5.2

(in no particular order)

Any comments or suggestions are welcome.

Best,

.........HI,

.........great list.

..............but dya have one using rybka 1 beta 32 bit only..?
.
.thanks

You do know that Sjeng 12.13 wont make it to the list, not even close.

I don't have many freeware engines. But what'd be cool is if someone has a freeware engine directory on their hard-drive who could zip it and put on a website. Or rather two directories, one for UCI and one for winboard

That would be a great gift to the community! That way people wouldn't have to go through the hassle of creating all the folders etc on their hard-drive

I'll do that myself if nobody else has one to go, but it'll take me a few months to get the engines I think

Glaurung 2.0 when it comes out soon

Glaurung 2.0 when it comes out soon

Thanks!

You can check where Rybka 1.0 Beta 32-bit stands in complete list, or in any of the sub-lists (like 32-bit single-CPU, etc, the links are on the main page below the rating list). Or you can just add it into my selection (my favorite method).

The list is not limited to 42 engines, but will grow as more engines are tested. For example, when Sjeng will be added, there will be 43 engines listed.

I am curious to test Sjeng 12.13 because it is the last free version of a program that turned commercial.

It is around the same strength as Betsy, Chezz etc. If I remember correctly there was a long absence before the release of the commercial version.

Yeah, first results show it is certainly weaker than the current bottom of my selection. Still it's a fine engine, more stable than some much stronger ones. And I don't have to worry about new version coming out tomorrow. (Though of course it will be great if new free Sjeng appears).
